The game has some design faults which I think sould be improved. First the music is a few tunes looping constantly, which is very irritating. After pausing to stop the music, I was presented to a menu with two options: Menu will cancel the game, and restart is continue. I pressed menu because I didn't want to restart, and then I lost my progress... (so please, change "restart" by "continue") Also, there is no indication on what you need to do to go to the next level, or how longer you need to survive.

In fact I like it, but I think you can do something better. Firstly, you need a better music. Secondly, a better background (black can be an easy choice).
